To all whom it may concern:

Be it known that I, FREDERICK South Bethlehem, in the county ofIslo'rthampton and State of Pennsylvania, have invented certain new anduseful Improve ments in Reed-Motions, whereof the follow-t ing is aspecification, reference being had to the accompanying drawings. r

My invention ing more easy relates to means for render the passage ofthe warp threads between the reeds of a loom, and also for.simultaneously distributing the wear occasioned'by the contact of thethreads and the shuttle with thereeds. It is. applicable to looms forweaving various fabrics and for weaving either narrow or wide webs.

To effect these purposes my invention consists ofa reed frame to whichis imparted a vertical reciprocatory motion in addition to its normalhorizontalreciprocatory motion. It willbe understood that I do not hereuse the term vertical and horizontal ina mathematical sense, for'the'vertical motion is not strictly such, owing to the varyinginclination of the lay, and the horizontal motion is not strictly such,becauseowing to the pivoting of the lay, the reeds move in an arc of acircle; butwith this explanation, Iwill use the phrases v ertic'alreciproca tion, and horizontal reciprocationfl to indicate these twodiffering motions of the reed frame always at rlght angles to ea chother.

play as it falls back, the movementbeing continuous throughout thestroke. In this way the reeds aregiven a'sliding motion asthey beatbackand forth along the warps, whereby the passage between two adjacent"reeds of any lump or enlargement of the threads, is rendered more easy,and the threads smoothed out so as to allow passage without breakage;and apart from abnormal the threads it is to be noted enlargement ofthat a Warp passes more easily over a reed or dent with which. it is incontact if the rela- Specification of Letters Patent.

OTT, of

According to my invention, for the, pure tive motions of the two have adiagonal resultant. fFor the purpose of accom lishing the other end ofmy invention, I ma e provision wherebythere is a constant variation inthe limits of the vertical position of the reed frame from heat to beat,having reference both to the position in which the lay falls differentportion of each reed in contact with the warps on either side of it ateach beat of the reed, thus effectually distributing the wear andreventing the formation of those well de ned variations" inthe'thickness' of the reed, due to wear, such as ordinarily o'ccurfatthat point of the reed which marks the limit of its contact with thewarps. In thislway I lengthen the life of the reeds. Likewise the samevaria tion in the vertical position of thereeds as they fall back causesa similar variation; in the line along which the shuttle rubs againstthe reeds as it traverses the raceway and in this way I distribute thiswear and prevent the formatlon of a corresponding groove 7 along theface of the, reeds. f

' back, and the position in which it, beats up. a This brings a slightlyIn the accompanying drawings, FigureI,"

is a sectional view showing the a plication' of my invention to a loom.Fig. I is a partial front elevation of the lay and reed frame.

"In said drawings,.the, lay 1 is mounted upon the swords 2, which arepivoted at 3 to each side frame 4 of the loom. The reed frame 5 holdingthe reeds 6 is secured on each end to a strap 7 having a boss 11 on itslower end through which'the shaft 8 passes. This shaft thus forms a suport upon which the reed frame is pivota ly mounted. Said shaft8'ismounted in the up er end of links 1( upon each side of the mac iineandis kept in p ace by'collars 17. A shaft 12 suitably journaled inadjustable bearings '13, on the side frames 4, is rovided with two eccentrics 14, about eac of which one of the links 10 is mounted to movefreely. The bearings 13 are slidably mounted onthe side frames 4 and maybe adjusted to vary'the position of the reed frame. The upper ends 9 oflinks 10 are free to'move in slots 15, in the swords 2. The swords 2 arealso provided with slots 16 into which the ends of the shaft 8 roject.Thus when the lay-1, is moved orward and backward in the act-of beatingup the filling thread,

the reed frame 5, is a new region of given a vertical recipro'catorymotion at right angles 'to the'beat of'the lay, and coincidenttherewith, that is to say, as the lay moves forward the reed frame iscontinuously lowered, and as the lay moves backward the reed frame iscontinuously raised. 1

This relative motion of the reed frame and lay takes place at each beatof said lay. This vertical motion of the reeds with respect to the warpthreads tends to smooth out any lumps or inequalities in said threadsthus insuring their free action to form the shed, and generally rendersthe passage of the warps between the reeds more easy. Owing to this facta cheaper grade of ma terial may be employed in the warp.

Extending downwardly from the front of each strap 7 is a rod 22, havingits lower end adapted to bear against a buffer 23, mounted in aconvenient position upon the frame of the machine, when the lay is inits forward position as shown in Fig. I. Secured to the upper front faceof each of said rods 22 is a metal strap 18, to which the lower end of aspring 20 is attached. The upper end of each spring 20 is attached to asword 2. These springs are comparatively light and tend to keep the reedframe in its proper position with relation to the swords, yet allowingit to move up and down with only a slight amount of friction. I

Power is applied to the crank shaft 30 having fast thereon the gearwheel 32. Said gear wheel 32 meshes with a gear wheel 33 secured to theshaft 34 j ournaled in the lower part of the side frames 4. The crankshaft 30 is provided with two cranks 36, one at each side of themachine, and said cranks are connected by means of links 38 with theshaft 8, by which the oscillatory motion is imparted to the lay 1.

Mounted upon the shaft 34 is a sprocket Wheel 35 connected by a chain 39with a sprocket wheel 40 on shaft 12.

The operation of the device is as follows: The lay -1 is oscillated in awell known manner through the connection of its swords 2 with the crankshaft 30 by means of the rod 8 and links 38. The rotation of the crankshaft 30 and gear 32 is transmitted by gear 33 to shaft 34 and sprocket35. Said sprocket 35 by means of chain 39 drives sprocket 40, and shaft12 connected therewith. It will be noted that the motion imparted to theeccentric 14 on shaft 12 is slow owing to the manner in which thegearing is employed to reduce the speed from the shaft 30 to shaft 12.Accordingly as the eccentric 14 rotates, a slow but constant variationis occasioned in the limits of the vertical motion of the reed frame 5,as imparted to it by the link 10, connecting said frame with theeccentric, thus constantly presenting a the reeds 6 for contact with thethreads and to the extent of said eccentricity. Furthermore, by varyingthe position of shaft 12 by adjusting its bearings the extent ofmovement of said reed frame may be further varied.

It will also be noted that when the lay is i moving forward to beat thefilling into its final position, the reed frame will be tiltedbackwardly if it were not for the engagement of the rods 22, with thebuffers 23 which tend to keep the reed frame in an upright position, andare aided by the springs 20.

It will be understood that I do not limit myself to the specific meansherein shown, as it will be evident that other means may readily beemployed for accomplishing the same purposes. Furthermore it willreadily be seen that I ma employ means for reciprocating the reed framevertically at each beat without the employment of the additional meansfor slowly Varying the limits of its vertical position. I may alsoemploy means for slowly varying the vertical position. of the reeds forthe purpose of distributing the wear thereon without employing means forreciprocating said reeds at each beat of the lay.

Having thus described my invention I claim:
